I have a 60D and have been searching for a lens that would be a good prime for portraits. I have an 85mm 1.8 which is good for head shots I know to avoid any facial distortion but I have also heard that the lens that most closely represents what the human eye can see is a 50mm.


My question is since I have to multiply by a factor of 1.6 when comparing against a full frame DSLR, that would mean that if I were to get the Canon 50mm f/1.4 I would actually be shooting at 88mm.


So in order for me to get the quality/benefit of shooting with a 50mm - should I then be looking at a 35mm like the EF 35mm f/2.0 which when multiplied by 1.6 is closer to being a true 50mm? or should I stick with the 50mm f/1.4 and just learn to step back further?


What I am looking for is to get as close to the human eye in perspective without sacrificing picture quality.


Thanks again for the help.
